Deflectable chair back

Abstract

The chair is preferably of the overstuffed type having a back which is separate from the seat. Brackets are provided on the sides of the seat and back forming a rod-receiving loop therewith. The loops are interconnected by heavy spring rods which permits the removal of the back for compact shipment and which permits the upholstered back to deflect relative to the upholstered seat frame and arms. The seat frame may be supported on a base by a rocking and swiveling mechanism or it may be fixed directly thereto.

I claim: 
     
       1. In a chair, a chair frame having a central seating area and an arm at each side, a supporting base, a back frame separate from said chair frame, upholstering material on said chair and back frames, a pair of unstressed spring rods for supporting said upholstered back frame at the rear of said chair frame to extend upwardly thereon so that the upholstering material at the sides of the back frame is in engagement with the upholstered material at the rear of the arms of said seat frame to provide the appearance of a continuous back frame on the chair frame, said back frame being deflectable rearwardly on said spring rods which are hidden beneath the upholstering material on said back frame which is in engagement with that on said arms. 
     
     
       2. In a chair as recited in claim 1, wherein said spring rods are straight with the upper ends supporting said back frame in a manner to conceal said rods. 
     
     
       3. In a chair as recited in claim 2, wherein said back frame is movable upwardly from the upper end of said spring rods and disposable on the seat frame between said arms for compact shipment. 
     
     
       4. In a chair as recited in claim 3, wherein a pair of brackets are mounted on the upholstered seat frame adjacent to the rear end of said arms, and wherein a pair of brackets is mounted at the sides of said upholstered back frame, the ends of said rods extending into said brackets for supporting said back unit on the frame unit in a manner to hide the brackets and rods between the upholstery material on said back frame and arms. 
     
     
       5. In a chair as recited in claim 4, wherein said brackets on the chair frame have an aperture forming socket which presents upwardly and said brackets on the back frame have aperture forming sockets which present downwardly. 
     
     
       6. In a chair as recited in claim 4, wherein said back frame is slid downwardly at the rear end of the arms into supporting engagement with the upper ends of the rods and with the upholstering material at the rear of the seat frame and arms and that at the sides of the back frame in engagement with each other.
